Application filed February 5,

To all whom it may concern:

- Be it liHOWIl that I Arrannns N. Kiirrscnin, a citizen of the United States, residing at Chicago in the county of Cook and i tate of Illinois, have invented a certain new and useful Improvement in Printing Frames, of which the following is a specif cation.

This invention relates to printing frames, and particularly frames of the type adapted for use in blue printing. It has for one object to provide frame wl ich may be made in large sizes and which will be easy of manipulation. Another object is to provide in such frame means for ready opening and closing. Other objects will appear from time to time throughout the specification and claims.

hfy' invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure l is a plan View with parts broken away.

Figure 2 is a vertical cross section on line 22 of Figure 1 on an enlarged scale;

Figure 3 is a view similar to Figure 2 showing the frame open and with parts omitted;

Figure 4 is a partial end elevation on an enlarged scale showing the frame operating handle;

Figure 5 is a partial end elevation show ing one corner of the frame;

Figure 6 is a fragmentary vertical cross section taken on line t36 of. Figure 4i;

Figure 7 is a detailed elevation on an enlarged scale of the cam shaped locking member shown in Figure 4;;

Figure 8 is a partial end eleiuition of the end of the frame opposite the operating handle l igure 9 is a vertical cross "ection taken on line 9- 9 of Figure l. showr i positioning mechanism.

Lil-{e parts are indicated by like characters throughout.

A is an open rectangular frame. lrlonnted across its top is a sheet of glass A which is held upon the frame A by means of the holding strips A? which are removably held in position. The frame A is mounted for rotation as a whole.

At either end yolres B B support the frame. These yokes carry respectively stub shafts B which shafts serve as trnnnions which support the frame for rotation. A locking means is provided which prevents accidental rotation as follows. The inner face of the yolre 33 i roughened in any suit able manner as shown at li The engaging member B which is mounted on the frame A. is correspondingly formed. The outer end of the stub shaft is reduced in diameter and threaded as at B See 9. Upon this threaded portion a controlling handle B is mounted. When it is desired to hold the frame in position to prevent its rotation, the controlling handle B is screwed tight and the faces of the members l3 and B are drawn together, and the parts are held in any desired angle of position. When it is desired to rotate the frame, the handle is unscrewed and the frame may be rotated. The frame is preferably arranged so that its center of gravity practically corresponds with the axis of the stub shafts, and thus even when free to rotate the frame does not have a pronounced tendency to turn or move of its own weight.

C is a removable felt pad (see Fig. 2) adapted to be placed over the matter to be printed which n'iatter is placed directly upon the glass. Above the felt pad C is a rubber (l which has about its edge a thickened contact portion (1- provided with two heads (3. f is a connecting hose through the ruhher pad This connection leads to any sui ble air et'l'iausting means not here shown its details form no part of the present invention. As the frame is closed the air is exhausted from within the onclosed portion bounded by the glass plate and the rubber sheet and a vacuum is created therein. This condition of course tends to hold the parts together to prevent their accidental displacement or slipping.

Above the rubber pad and pivotally nonnted on the sides of the frame A are four side frame members D. These members when moved. to the closed position as shown in Figures l and 2 constitute in effect rectangular frame and hold the matter to be printed on the belt and rubber sheets in position. They are, however, not joined to gether at their corners, and thus when raised into the position shown in Figure 3 they are separated.

Each of the frame members D is supported from the frame A means of two or more pivoted arms E. These arms are pivoted at E in a bracket member E which is secured to the side of the frame A. The frame members D are preferahly spri n held in the members E. For this rmrpose the holding screws 3' fit loo in the member E to permit relative movement. but are fined in the frame members D. Between frame members I) and the members mounted leaf springs E. hese springs yield under pressure when the frame is closed and thus permit a tight fit. but on ion the entire mechanism from sl oc. t avoid the possihility of hrealrint the or other wise injuring any of the mate during operation.

Pivetally mounted on the member lL- at its oettom is a lever F, see Fig. 8. This lev r is pivotally connected its upper end to a second lever F which is connected to the member at its upp I hy a hall join. and forked at its lo .er end for connection with the lever F. The levers F and 1 form together a knuckle joint arrai I emcnt which when the frame is closed lie to 'ether in the position. shown in full lines 1. Figures t and 5. and when the frame is opened are pulled laterally i .30 the position shown in dotted lines in Figures 4; and It will be noted particularly from Figures 4: and 5 that when the frame is closed the levers F and F are moved so that their ivotal connection lies slightly to one side of a line d awn between their outer ends. Thus by reason of their position they are locked against accidental movement.

Extending; laterally about the frame is an operating connection formed of a plurality of bars (i and chains (i The hers lie along the sides of the frame and the chains extend about the corners and connect the hars. At each of the corners the chain is carried by a sprocket wheel G This wheel is mounted at tl ree of the corners on a shaft and is adapted to rise and fall alone: the shaft as the frame is opened or closed. During this operation it moves from. the position shown in full lines in Fig.1". 4t and 5 to that shown in dotted lines. one of the corners. namely. that at which the operating handle is located, the sprocket wheel G is fixed on a shaft G" and this shaft rises and falls and the wheels move with it. The ieft has at its upper end an operati handle G and has mounted on it a guidin... and controlling cam H. This cam is provided with the curved face H and the stop member H which serves to prevent erzcessive rotation of the controlling handle and the shaft. hen the frame is fully clos d, the cam is in the position shown in Figure t. and in that position the short fac H" of the cam H contacts one side of the bearing; frame H which carries the shaft G lVhen the frame is completely opened the long face.

lit contacts the other side of (one H and thus excessive the controlling handle and in either direction is prevented.

the use of the fran'ie it is frequently .hle to open only a portion of the frame inspect the work or for any other reason, is the; fore desirable to hold the work vi i1 frame against slippin For this pur 'iose I provide means whereby one end of the frame can he held closed when the it is open. This means is illustrated am 8. As there shown the i to the other and its operation is gener- ,0 that of oars G do not directly operate and closing mechanism. The ow the lznucl'ile joint of the and there is mounted above j connecting bar I. This liar the lovers ll and. ll at their mnnectioiii and when moved laterin the following manner. he oar has in its upper face a notch l and it has plvotally upon it an Ol "1 'lllg lutCll P.

e 1e ure 1, in wh ch the glass side is down. The

rue other frame mom-- ower the frame closing means in the manner controlling handle is then operated and all rubber sheet is then moved away and also the felt pad. The material to be printed is placed in position against the The felt is replaced and the rubber sheet replaced and the side frame members are replaced, and closed holding the assembly of the printing material in position. Air is then cxnausted from the space confined. between the rubber sheet and the glass and printing may commence. The frame is then rotated to any suitable angle and'ismoved so that the light either artif cial or of the sun lies in the proper manner upon the glass and so the printing may take place.

The removal of the material is exactly the same as that above described for fillii'ig, except that the order of the operation is reversed.

When it is desired merely to look into the frame and not to remove the material from it, one of the end frame members is disconnected and then the operation of the controlling handle does not affect it, and it remains closed while the other side mom-- here are opened.
